Best For home recording: Donner Dual Input DI Box

Buy on Amazon

Best part: donner dual input di box costs comparatively low and it is available to ship in 24 hours. It's a compact passive direct box that is perfect for guitartbasses and keyboards. It is magical in its ability to handle extreme signal levels with a natural compression that is pleasing to the ears. The input is connected to a single coil, and this is placed next to 2 coils which connect to the XLR output. The output impedance of the di box is directly correlated to the number of windings in the output coils, but only slightly correlated to the impedance of the input coil, so there is no need for a switch or a separate coil to accept different inputs.

This direct box does NOT have noise suppression built in. There is nearly no complaints, it’s small and versatile, it’s simple and effective, and all this for only around $30, yes please. It's a great passive DI for any home studio or live application.

Best For synth: Radial Engineering Dual Input DI Box

Buy on Amazon

The radial engineering dual input di box should be able to handle its purpose and duties with ease. This DI has a ground lift on both sides, input and output section, totally isolating and eliminating all possible grounding issues. It can be used as an instrument di (for 2 separate instruments) sending the thru to an amp. It will take a direct feed from an iPod or computer via the headphone jack, or if you've got a iPod 30pin breakout cable it will take the line level as well via stereo RCA's or 1/4" connections.

The composite inputs and the 1/8" TRS inputs are great to keep from having to use adapters on the cables. It has a left and right channel that can be split and used as two mono channels. This is a substantial piece of gear.

• Excellent di box for feeding your mixer
• Good brand reputation

Best For Ipad: ART Dual Input DI Box

Buy on Amazon

The art dual input di box is satisfactory and appropriate and fits well with your daily purpose. The DualXDirect provides two independent high quality active interfaces that let you connect instrument, line, or speaker level signals to a mixer or other balanced inputs (microphone xlr connections, 1/4" line level phono plugs like a guitar, etc) to a standard balanced low impedance signal output. It converts various high impedance balanced and unbalanced inputs (microphone xlr connections, 1/4" line level phono plugs like a guitar, etc) to a condenser mike through the input port. It makes it "powered" and the signal going to the mixing board is boosted or hotter.

If the amplifier you are feeding has phantom power, the ART will run off of that phantom power. It's also good to use for having a local amp (fed from the front side passthrough jack) as well as feeding a combined PA amp. It does not supply phantom power to a condenser mike through the input port.

• Well built and runs great off of the phantom power from the mixer
• Very quite and lean sounding direct box
• Works on 9v battery or phantom power

Best With volume control: ART Direct Box
